Trait ExecutionMonitor 

pub trait ExecutionMonitor: Send + Sync {
    // Provided methods
    fn pre_execute(&self, _task: TaskId, _at: Instant) { ... }
    fn post_execute(
        &self,
        _task: TaskId,
        _at: Instant,
        _took: Duration,
        _ok: bool,
    ) { ... }
}

Hook invoked before and after every execute call. Defaults are no-ops.

Provided Methods

fn pre_execute(&self, _task: TaskId, _at: Instant)

Called immediately before an item’s execute() is invoked.

fn post_execute(&self, _task: TaskId, _at: Instant, _took: Duration, _ok: bool)

Called immediately after execute() returns. ok is false if the item returned Err (or panicked).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
